I think we all have a certain song, or group that we listen to when responding to a fire (yes I know the FD pagers/radios are in the background) whats your personal favorite song to get you pumped?
Driving Code 3 in urban areas where the potential for disaster truly exists, necessitating 100% attention is much different than responding code with a strike team of Type III's mutual aid on freeways and rural roads where there is no hazards present.
It's a matter of time of day, hazards, people, type of road, etc. When nothing but waiting to get to a call is involved, and typically, I'm referring to wildland responses, inter hospital transfers, middle of no where responses that afford you and your crew to reduce stress levels by listening to mutually acceptable music by mellow soothing groups like LMFAO.
